Ok I checked Pin 13 by grounding it and it can be seen changing state in the Hal show.

Where do I look now? I really should of looked into the Gecko 320x more before I brought them, Its becoming a real pain in the ass to get these things to work properly.

Or maybe I am facing problems because the power supply for the reset/error circuit is coming from the drives themselves, would I be better off by wiring the circuit from the spare step and direction pins on the Mesa 7i76e?
